I asked a few native speakers about which phrase was more natural in a situation where I ask a friend if they had time:




They all chose the latter. So is the former unnatural? In what situations would you use it in?

    I have no supporting study to back up this claim. I posit that the transition from the k-sound from 間 to the g-sound from が (two velar sounds), is less smooth than the transition from 間 to the w-sound from は. I suppose a way to check this is to measure the は・が preference of deaf/mute Japanese, and compare it to the preference for non-deaf/mute.

    @Flaw It's exactly the same situation with all 「○○(が/は)ありますか?」 sentences (i.e., は is almost unilaterally the correct choice for question sentences). In addition, 「時間があります。」 is just fine (especially when there's some extra qualifier or explicit topic in the sentence), despite the same //kanga// sequence. So, I really don't think it's a phonological phenomenon. Jan 29 '16 at 19:44

I'm amused to read all of your native Japanese speaking friends chose 時間はあります. To me 時間があります and 時間はあります sound the same, and look interchangeable as a postpositional particle - は、が following the subject..

If I was asked which of が and は I would choose in the following examples, I would choose






But it doesn’t mean the other option would be grammatically wrong.

Frankly I don’t know why I chose them this way. It might be just intuitive for me, and it is a matter of taste at best. I don’t think the choice of は and が makes any significant difference in meaning or grammaticality in most cases.

  • It might be slightly confusing since in "If I was asked which of が and は I would choose in the following examples", が is the former and は is the latter. But in the subsequent examples, the order is reversed such that は is the former and が is the latter. There is confusion in the closing statement "Frankly I don’t know why I chose the former than the latter".

    `Flaw. Regarding the closing statement, "Frankly I don’t know why I chose the former than the latter,".I said so because I can't offer grammatical justifications about my choice, as I'm not academic grammarian. I'm just talking based on my 83 years of experience of living as a Japanese who is interested in reading and intuition. Jan 29 '16 at 7:02

    I did not mean the conclusion itself was confusing. I was referring to the possible mix-up of what "former" and "latter" refers to. It looks like that has been cleared up in an edit, so the confusion has been resolved.

As a native speaker, I would also definitely choose your second sentence using 「」 if you just asked me:

"Which phrase is more natural in a situation where I ask a friend if they had time?"

without giving any more specific information. In other words, the exact context. What is the situation in which you are asking this friend if s/he has time? What exactly did you and/or s/he say immediately before you uttered the sentence 「時間( )ありますか?」, etc.?

Japanese is an extremely contextual language; Context is king. And believe me, that is still an understatement.

With over three decades of experience with Japanese-learners, I know well that their "favorite" subject marker is 「が」 for the reasons I have yet to understand to be honest. Many use it as if it were the default option.

You need a good reason to use 「が」 over 「は」, but the question "Do you have time?" is so generic in nature that choosing to use 「が」 is not only fairly unnatural but is also highly unjustifiable.


It's not technically impossible to use 時間が… for questions (unlike sentences of statement that represent speaker's judgement) but it may sound like you suspect that they have time. Usually, you use a sentence that contains some topic when you ask people and expect them to reply, for them to follow the topic you have staked.


One option that might be overlooked is to omit the particle, as opposed to choosing "は" or "が". In this case, it would sound much closer to "は" than "が".

Personally, I would go with this third option, in most cases.

Nonetheless, I concur that context really is important when discussing Japanese. There are cases when one would sound correct, and the other incorrect and vice versa.

In what situations would you use [the former] in?

When the subject is made clear to be someone other than the listener.
